“…Cependant, des tendances générales ont été observées, notamment avec la présence de manganèse qui apparaît plus marquée sur les premières strates du biofilm, alors que lorsque la colonisation par les diatomées est plus importante (Figure 2 : rectangle à droite), le manganèse n'apparaît quasiment plus. Lors des premières étapes de formation du biofilm, les bactéries sont les principales « colonisatrices » dont certaines sont capables d'oxyder le manganèse (MIYATA et al, 2007). Le Mn incorporé sous forme dissoute dans les bactéries au sein du biofilm s'oxyde majoritairement en MnO 2 (MIYATA et al, 2007).…”

“…Les biofilms sont surtout constitués d'agrégats cellulaires bactériens emprisonnés dans une matrice de polysaccharides (COSTERTON, 1999), d'algues (diatomées, chlorophycées) et sont capables d'assimiler de nombreux minéraux (HIERNAUX, 2005;MIYATA et al, 2007;MORIN et al, 2008;QUINTELAS et al, 2009). De plus, certains éléments peuvent perturber la structure des diatomées (CONWAY, 1978;DE LA ROCHA et al, 2000) et par conséquent influencer la structure des biofilms.…”

“…Il peut présenter différents états d'oxydation dans le milieu naturel (II, III, IV). À des pH proches de 7, le manganèse contenu dans l'eau est majoritairement sous forme Mn (II) et est incorporé au sein du biofilm puis oxydé par les bactéries (P. putida, L. discophora) ou les champignons (ascomycètes) en MnO 2 (MIYATA et al, 2007). Néanmoins, l'oxydation du Mn (II) par les spores de Bacillus pouvait passer d'un degré d'oxydation IV via un degré d'oxydation intermédiaire Mn (III) (WEBB et al, 2005).…”

“…Néanmoins, l'oxydation du Mn (II) par les spores de Bacillus pouvait passer d'un degré d'oxydation IV via un degré d'oxydation intermédiaire Mn (III) (WEBB et al, 2005). Certains éléments comme le Zn (II) et l'As (V) s'adsorbent très bien sur les oxydes de Mn (TANI et al, 2004;MIYATA et al, 2007). Cependant, il existe des interactions avec les oxydes de Mn pouvant limiter l'adsorption de certains métaux comme l'As (V) notamment par la présence de Ni (II), Co (II) (BANFIELD et HAMERS, 1997).…”

C urrently, technology is looking for smaller scale, ordered materials with well-defined properties. Nanophase materials are, therefore, being manufactured in increasing numbers. 1Ϫ3 Nature is also a prolific producer of nanophase materials. A typical example of this is the microorganism assisted, or biogenic, oxidation of water-soluble metal ions into insoluble oxides. 4 Indeed this process has been taking place for millions of years leaving its signature all around: in the sediments on the ocean floor and in the soil on land. Nature's evident success is inspiring and scientists are trying to employ its tools for applications including manufacturing of magnetic nanoparticles 5 and capturing of contaminant metal ions. 6Ϫ8 Thus understanding the way living microorganisms produce materials, in particular nanophase metal oxides, is becoming important not only for the advance of today's technology but also for remediating some of its unwanted consequences such as metal pollution.One of the most important prerequisites to understanding a physicochemical process, such as the formation of a nanophase material, is the knowledge of the atomic-scale structure of its product. Recently, good progress has been made in determining the structure of synthetic (i.e., man-made) nanophase materials by employing total X-ray diffraction (XRD) involving a combination of high-energy XRD and atomic pair distribution function (PDF) analysis. 9Ϫ11 This nontraditional approach has also been applied to nanophase materials of geological interest, such as ores. 12 The approach can also be applied to materials freshly produced by living microorganisms. As an example we consider MnO x produced by bacteria and fungi. These biogenic materials show a length of structural coherence of about 2Ϫ3 nm only and, in this sense, are in a nanophase state. Nevertheless, their atomic-scale structure is periodic and can be described in simple crystallographic terms. Surprisingly the crystal structures of fungal and bacterial MnO x turn out to be substantially different indicating that biogenic materials are inherently structurally diverse.Manganese oxides are ubiquitous in nature 13 and have been used by mankind for many thousands of yearsOfirst as pigments and today as catalysts and battery materials. This has generated a long-lasting interest in their genesis. Several studies on MnO x produced by microorganisms have been carried out but no complete structural determination has yet been performed. The studies have only suggested that bacterial MnO x is likely to possess a layered-type structure of the type found in the mineral birnessite. 14,15 Even less is known about fungal MnO x . 16,17 *Address correspondence to petkov@phy.cmich.edu. As such, they are difficult to characterize structurally. In this report, we demonstrate how high-energy X-ray diffraction and atomic pair distribution function analysis can be used to determine the atomic-scale structures of MnO x produced by bacteria and fungi. These structures are well-defined, periodic, and species-sp...
